Delivering a reliable, professional solution for sports turf, amenity grassland and managed landscapes, Priest’s triple-action formulation combines highly effective active ingredients for fast visible results and long-lasting control of difficult and persistent weeds.

Florasulam – an ALS inhibitor providing systemic control of many common broad-leaved weeds
Fluroxypyr – synthetic auxin herbicide effective against woody and deep-rooted species
Clopyralid – systemic auxin herbicide particularly effective on thistles, docks and legumes

Together, these ingredients offer effective control of species including Daisy, Dandelion, White Clover, Ribwort Plantain, Common Mouse-ear, Selfheal, Sorrel and Slender Speedwell. In addition, moderate control is also achieved on Bird’s-foot Trefoil.

The versatility of Priest is matched with flexible application through either powered or knapsack sprayers, with just one application needed between March and October for optimal results. Priest is also safe to use on a wide range of turf grass including Annual Meadowgrass, Perennial Ryegrass, Chewings Fescue and Creeping Bentgrass though a test should always be carried out before full treatment, particularly on unknown turf cultivars.

Commenting on the newly launched product, Nick Martin, Commercial Director, said: “We are delighted to introduce Priest to the Origin Amenity Solutions product portfolio. Bringing high-performing, reliable solutions to the market is central to our commitment to customers, and Priest is another excellent example of that.”

“Priest is something we’ve been working on for a while and I’m delighted to have seen its efficacy first-hand” adds Mark De Ath, Origins PPP Team Lead. “It’s control of such a wide range of weed species will see Priest become a key tool in the armoury of all those looking after managed amenity turf and amenity grassland.”
